Product Details

The PMA-720AE is equipped with an Advanced HC (High-Current) Single Push-Pull Circuit that enforces Denon's design concept for pure audio amplification. This design ensures that you hear delicate musical details, reliably supported by plenty of power. Playback faithful to the original sound is also made possible by a circuit board layout that can handle the greater power from the amplifier section and appropriately respond to the output level and unique character of the signal. In addition, the internal construction of the PMA-720AE has been carefully designed to prevent unwanted vibration from adversely affecting the audio signal.

High Current (HC) Single-Push-Pull Circuit for musical detail and powerThe PMA-720AE incorporates HC transistors with 2 to 3 times the electrical current supply capability of conventional power transistors for audio. Denon's acclaimed HC Single-Push-Pull Circuit has been inherited from its high-end models which, together with a fully discrete amplifi er design, produces a powerful sound fi lled with beautiful musical details.

High-speed, high-capacity power supplycircuit for HC Single-Push-PullThe PMA-720AE's power circuit uses a block capacitor that Denon engineers have jointly developed with a parts manufacturer and a Schottkybarrier diode that features low internal resistance for low loss, short recovery time, and negligible rectifying noise. This highly stable electrical current supply further brings out the expressive power of sound produced by the HC Single-Push-Pull Circuit.

Wide dynamic range, supporting high-grade audio sourcesThe PMA-720AE's tone control and power amplifi er circuit have been carefully adjusted to secure a frequency response of up to 100 kHz during actual use. Also, improvements in the volume circuit suppress noise in the amplifier to achieve high sonic resolution. These features and others give the PMA-720AE plenty of latitude to handle the wide dynamic range of high-grade audio sources such as Super Audio CD and DVD-Audio.

Main transformer with separate power supplies for analogueThe coiled wire within the power transformer for the audio signal and control circuits has been separated to eliminate mutual interference and adverse infl uences on sound quality. The PMA-720AE also has a separate transformer to minimize power consumption when in "standby". Ensuring a more environmentally friendly design.
